a simple, eicientfand conveniently operated imple'n'ient foreiectinglthe removal of a sleeve in most rapid manner and'withoutinjurin g the same.

,More,specificl obje-cts andadvantages of `invention will :appear in thefollowing description.

The invention consists in the mechanism illustrated inthe accompanyingdrawing, in

which :Figurej 1 vertical ilo'ng'itudinal` sectional view 6i' animplement embodying my v im n 'mi f.' i .i l yinvention shown. appliedfFig. 2 1s a plan view of theimplementfandFig. 3 is a vertical 'l')ngitucli1ial, sectional vview oi the rleft handportion IVofhfig. 2. y

.'lii said drawing `the reference numeral 11 represents an axleextending through a housing 5 which has at its outer end a cylindricalcavity 6, tor a sleeve 7 which constitutes the outer memberof a rollerbearing assemblyk (not shown) for said axle. Adjacent its inner end andat the top of its peripheral wall the sleeve 7 is provided with a hole 8which registers with a hole 121 in the housing, through which holes alubricant is supplied to the bearing assembly above re- Ylerred to.

Said sleeve is of the contractileftypethat is to say, the sleeve isformed to have an Y external diameter slightly? greater than thediameter of said cavity and is provided in its periphery with a slot 9ext-ending longitudinally its entire length, thereby permitting thesleeve to be contracted for insert! ing the same within the Vhousingcavity. Said sleeve 1s held in place within said cavity because of itstendency to assume its nor- `mal size diametrically, and also bytheprovision upon the sleeveot` a protuberance 10 which engages in anaperture 11 provided Vin the peripheral Wall 12 of the cavity.

In practice, the outer end 13 oit said sleeve is located in a verticalplane either Within said cavity or coextensive with the extremity 14 ofthe housing Wall 12, thus aiording'no projecting` porti-on of the sleeveWhich can be grasped by an extracting tool.l

In carrying out the invention, I provide a tubular easing member 15having at one fend a cylindrical head 16 of a diameter to provideaslidable fitwithin the sleeve. bead'is Vprovided with a radiallydisposed bore 'lor a cylindrical stud 17 'ljiaving a peripheral Agroove18 into which extends the end or" a retainer screw `19. Thewidth ofAthe,groove d8 is such as will permit axial mf vement of thestud-sul'hcient vto enable its being` thrust outwardly from itsIsheathed rposition (Fig. 3) within the vhead 16i`nto ftheoil hole 8 'otv the sleeve when 'the 'latter iste-be coupled with said casing member.,

Being located in the upper portion of the `casing head the stud 17 isnormally held by gi avitation. in the-sheathed position in which itis'illustrated in Fig.r 3andkr`when 'thus dispoedtlie lower lend `20ctthe stud extends into the. bore or" said casing. y y Extendingaxiallyinto said casing borevis a tubular member 21, hereinafter termedthe controller, n u y i/Vithin 'the casing, the controller is providedwith a tapering external surface 22 which, in an advancing movement otthe controller, tunctions as a cam to cause the stud to be protrudedtrom the outer periphery oi the casing member.

The controller is advanced or retracted axially or the` casing member bymeans of internal screw threads upon the latter cot d ,red operable byturning the controller in*r one or the other rotary direction.

To permit the two aforesaid members to be iirmly grasped in the hands otthe operator, portions 2e and 25 of the outer peripheral surfaces or'the casing and controller are desirably knurled.

26 isa scratch mark or groove disposed longitudinally olf the casingmember and in a vertical plane with the axis of the stud 17; and 27 is ascratch mark or groove extending eircumierentially about the casing andindicates with respect to the end 18 of the Sleeve the extent of theinsertion oi' the casingin the sleeve to position the stud'in engageablerelation with oil hole 8 of the sleeve.

To apply the device so far described, the casing and controller membersarranged as shown in Fig. 3, are inserted within the sleeve and, afterpositioning the casing member by means of the scratch marks 26 and 27,the controller is rotated to advance the same through the medium of itsthreaded engagebij and acting against the end of the axle, which t isprovided with a Center-punch hole to receive the pointed end et saidserew.

1Wha l claim, isfl. An implement for removing a rollerbearing` sleeve:troni the housing of an aille, Comprising two tubular members, one ofsaidmembers extending into the other inember and eonneeted thereto foraxial adjustment, said inner member being provided with internal screwthreads, a sleeve engaging stud niounted for movement radially of theoutermember in the peripheral Wall oi the latter, means provided uponsaid inner member and engageablevnf'ith said stud for protruding thesame from the outer member,

and a screw extending` axially into said inner member and engaging thescrew threads thereof :For the purpose hereinbeiore described.

2. In an implement for removing an apertured roller-bearing sleeve froman axlehousino' a tubular easine member a stud mounted therein 'forlimited movement radi-l ally of said member, and a tubular Controllerextending into said member and Connected thereto. by serew threads forrelative axial movements, said controller being formed with a taperingportion and rendered operative byan axial movement et the Controller toprotrude the stud .from the Yeasing member into the aperture of saidsleeve to couple the latter with said casing men'iber.

3. ln an implement tor removing a rollerbearing sleeve from the housingof an aXle,

` said sleeve having an aperture in its periphery, a tubular easingmember adapted to be inserted within said sleeve, a stud mounted in saidmember ior movement radially thereoi'finto the sleeve aperture, saidstud being normally retained by gravitation in diS- engaged relationwith said sleeve, a eontroller member extending into the Casing memberand having a tapering end, said Controller being movable axially of theeasing member to cause said tapering end to eli'eet a sleeve-engagingmovement t0 the stud, and means acting through the medium ot both of'said members and with Vrespect to the axle for the purpose ofwithdrawing the sleeve from the axle housing.
